Did this change recently? I've definitely OLCI'd for international flights ex-ORD before.
Or is it a visa issue? I just realized Vietnam is not part of VWP.
You can OLCI, you just get a "check-in confirmation" instead of a BP. OP is also connecting onto HAN, which has additional visa restrictions that require passport check.
